About this app

Coach Fartlek is a proactive AI running coach for serious recreational runners. It builds your training plan, analyzes every workout, tells you what is holding you back from your race, and reaches out when it matters, just like a real coach would.

WHAT YOU GET

• Personal training plan — a weekly running schedule tailored to your goals, races, calendar, and how your body is responding right now.
• Proactive coaching — messages after every run, before key sessions, and when recovery should take priority.
• Smart recovery — resting heart rate, HRV, sleep, and training load are combined so hard sessions land when you're ready.
• Race focus — from 5K and 10K to half marathon and marathon: clear mesocycles and peaking strategies toward race day.
• Five factors — VO2max, threshold, running economy, endurance and anaerobic capacity: the coach reads them from your running and shows which one limits your race goal.
• Training journal — your full running history in one place. The coach remembers what you've done and what works.

A TEAM AROUND YOU

Your coach works with a team: Stark for strength, Laktat for physiology, Fika for nutrition and Fokus for the mental side. They answer in the same chat, and the coach brings them in when a question is theirs. Pro includes Stark and Laktat; Elite the whole team.

THREE LAYERS OF PLANNING

1. Macro — the full season toward your A-race.
2. Meso — four-week blocks with the right load curve.
3. Micro — this week's sessions — easy runs, intervals, tempo and long runs — adjusted to your calendar and recovery.

SYNC YOUR WORKOUTS

Connect your Intervals.icu account and your runs sync automatically from your sports watch (Garmin, Polar, Coros, Suunto and more). The coach analyzes every workout — pace, heart rate, splits, intensity — and gives you feedback right after it syncs.

WHO IS IT FOR?

Runners who train consistently, have goals that matter, and want a running coach who understands both training and real life. Whether you're chasing a sub-3 marathon, your first half marathon, or a faster 10K. You need a sports watch: the coach works from your real data. And it does running only, from 5K to the marathon. That focus is the point.
